Book excerpt: Concentrating solar power with thermal energy storage (CSP-TES) can provide multiple benefits to the grid, including low marginal cost energy and the ability to levelize load, provide operating reserves, and provide firm capacity. It is challenging to properly value the integration of CSP because of the complicated nature of this technology. Unlike completely dispatchable fossil sources, CSP is a limited energy resource, depending on the hourly and daily supply of solar energy. To optimize the use of this limited energy, CSP-TES must be implemented in a production cost model with multiple decision variables for the operation of the CSP-TES plant. We develop and implement a CSP-TES plant in a production cost model that accurately characterizes the three main components of the plant: solar field, storage tank, and power block. We show the effect of various modelling simplifications on the value of CSP, including: scheduled versus optimized dispatch from the storage tank and energy-only operation versus co-optimization with ancillary services.

Book excerpt: Concentrating solar power (CSP) deployed with thermal energy storage (TES) provides a dispatchable source of renewable energy. The value of CSP with TES, as with other potential generation resources, needs to be established using traditional utility planning tools. Production cost models, which simulate the operation of grid, are often used to estimate the operational value of different generation mixes. CSP with TES has historically had limited analysis in commercial production simulations. This document describes the implementation of CSP with TES in a commercial production cost model. It also describes the simulation of grid operations with CSP in a test system consisting of two balancing areas located primarily in Colorado.

This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power tower concentrated solar power (CSP) plants are capable of producing extremely high temperatures, as they have the ability to oversize their solar field and achieve a greater concentration ratio. This theoretically allows power towers to use more efficient, higher temperature cycles including air Brayton and supercritical Rankine cycles, as well as experimental cycles such as the supercritical CO2 cycle. As part of this thesis, the heat demand of each cycle, as well as the cycle diagram is examined for its suitability for use with CSP plants with thermal energy storage (TES). This will help develop criteria to determine if these cycles could be coupled with a higher temperature storage system. After the general cycle overview, this thesis describes the development, validation, and results of a TES system targeted for use with an air Brayton power cycle. This research analyzes the use of metal alloys as phase change storage materials and makes a case for their use with CSP plants. The numerical model developed here is intended to analyze the performance of high temperature systems suitable for thermodynamic cycles that do not have a commercially available storage system. The storage system essentially combines a heat exchanger and storage system to help realize potential savings over molten salt two-tank storage systems currently employed by industry. FLUENT computational fluid dynamics software is used to model the storage tank. After initial modeling of a hypereutectic binary alloy system it was discovered that FLUENT does not properly account for an individual material phase diagram. So, the thermal properties were altered in FLUENT in order to accurately reflect the thermal performance of the primary storage material chosen for study, AlSi. The model was also analyzed with pure metals and eutectic binary alloys in an effort to achieve stable air temperatures that could support an air Brayton turbine. These included both cascaded and non-cascaded geometries as well as reversed and non-reversed flow. The results of the cascaded models show that the heat exchanger/thermal storage concept is able to buffer the air entering the turbine, and produces relatively stable outlet air temperatures. It was found that using a single, pure metal as the storage material produced the highest, most stable air temperatures of the systems studied. With further optimization and research, this system could become a viable storage option for CSP plants in support of higher temperature cycles.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world increases renewable energy deployment, there is an increasing interest in hybridizing various generation and storage technologies to maximize net benefit to the developer and/or off-taker. A particularly interesting combination of renewable technologies is concentrating solar power (CSP) with thermal energy storage (TES), photovoltaics (PV), and electrochemical battery energy storage (BESS). Due to the system complexity of CSP technology, it is difficult to evaluate the technological and financial performance of a CSP-PV hybrid system without detailed modeling of annual operations. To address this challenge, we have developed a modeling framework for evaluating the performance and financial viability of CSP systems hybridized with PV and battery technologies. This modeling effort incorporates CSP tower and trough systems into an existing modeling tool recently developed by NREL referred to as the Hybrid Optimization and Performance Platform (HOPP). This report outlines the modeling methodology as well as preliminary results from example case studies conducted using the model. The methodology describes: (i) the integration of CSP tower and troughs into HOPP using python interfaces to access System Advisor Model (SAM) underlining technology models, (ii) the mathematical formulation of the mixed integer linear program dispatch optimization model which optimizes operations of storage asset to either maximize system revenue or minimize operating cost while load following, (iii) the design analysis methods implemented within HOPP, and (iv) simulation clustering for the purposes of reducing computational expense. We exercise the model using a case study of a future scenario where we assume (i) CSP and PV technologies achieve the 2030 cost targets provided by the Solar Energy Technologies Office (SETO), (ii) battery costs reduce to the 2030 mid cost projection presented by NREL. Lastly, (iii) electricity prices for southern California in 2030 are provided by NREL's Cambium database, and (iv) a capacity payment of $150/kW-yr based on the system capacity factor during the to 100 net-load hours.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on latent heat storage, which is one of the most efficient ways of storing thermal energy. Unlike the sensible heat storage method, the latent heat storage method provides much higher storage density with a smaller difference between storing and releasing temperatures. Thermal Energy Storage with Phase Change Materials is structured into four chapters that cover many aspects of thermal energy storage and their practical applications. Chapter 1 reviews selection, performance, and applications of phase change materials. Chapter 2 investigates mathematical analyses of phase change processes. Chapters 3 and 4 present passive and active applications for energy saving, peak load shifting, and price-based control heating using phase change materials. These chapters explore the hot topic of energy saving in an overarching way, and so they are relevant to all courses. This book is an ideal research reference for students at the postgraduate level. It also serves as a useful reference for electrical, mechanical, and chemical engineers and students throughout their work. FEATURES Explains the technical principles of thermal energy storage, including materials and applications in different classifications Provides fundamental calculations of heat transfer with phase change Discusses the benefits and limitations of different types of phase change materials (PCM) in both micro- and macroencapsulations Reviews the mechanisms and applications of available thermal energy storage systems Introduces innovative solutions in hot and cold storage applications

This book was released on 2019 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concentrating solar power (CSP) with thermal energy storage has the potential for grid-scale dispatchable power generation. Thermochemical energy storage (TCES), that is, the reversible conversion of solar-thermal energy to chemical energy, has high energy density and low heat loss over long periods. In this work, we develop optimization-based models for the design and analysis of CSP with different fluid-phase and solid-gas TCES systems. By proposing various TCES process strategies, evaluating their system performance, and identifying key areas of improvement, we hope that our study will help accelerate TCES development and solar power deployment. Specifically, we first develop a general process model for CSP plants employing fluid-phase TCES systems. We illustrate our model applicability by using ammonia and methane TCES systems. The analysis allows us to identify pressure vessels for aboveground gas storage as the main cost driver and compressor electricity consumption as the main energy driver. The overall energetic and economic performance can be significantly improved if cheap underground gas storage is available. We then propose an optimization-based framework for process synthesis under variability in two frequencies. We introduce scenarios and modes to represent low and high frequency variability respectively, and formulate the synthesis problem as a multimode two-stage stochastic programming model. The proposed approach is well suited to address the synthesis of renewable energy systems where the energy resource (e.g., solar, wind) often exhibits variability in two scales. Next, we develop an optimization model for the design and operation of CSP plants employing solid-gas TCES systems. Special emphasis is placed on the modeling of fixed-bed reactors that operate in a cyclic batch mode, which are modeled using partial differential equations in time and space. Finally, we provide a system-level analysis for CSP employing various solid-gas TCES strategies, that is, different combinations of chemical reactions and process configurations. Six process configurations are proposed and three types (carbonate, hydroxide, and redox) of reactions are studied. Results show that, six out of the nine strategies have the potential to improve energy efficiency and reduce costs at the same time over two-tank molten salt storage. We also analyze the impacts of key reaction properties and process parameters on system performance.
